Clayton Kershaw and Brian Wilson might be on the disabled list because of the Dodgers' shortened spring training before they opened the season in Australia, but the team's hitters appear to be completely unaffected.

The Dodgers are alone in first place in the National League West, in large part because of their offense, which had another spectacular day Sunday in an 8-6, sweep-sealing victory over the Arizona Diamondbacks at Chase Field.

Adrian Gonzalez homered for the fourth consecutive game, Matt Kemp and Juan Uribe also belted home runs, and Dee Gordon swiped a career-high four bases.

So far, they look as if they will avoid the kind of slow offensive start they had last season, which was the main reason they were in last place at the end of June. By this stage last year, there were already signs of trouble, as they were shut out three times in their first 13 games. This year, they are yet to be blanked.

"This is kind of what you envisioned, a team that can go up and down the order, where a lot of guys are dangerous," Mattingly said. "I think that's what you're seeing."

The Dodgers have scored four or more runs in seven of their last nine games and six or more in five of their last six.

Chase Field was a factor, according to Gonzalez.

"When you come to a park like this that's a good place to hit, you're more aggressive, you feel better as a hitter, overall," Gonzalez said.

Their most consistent source of runs continues to be Gonzalez, who leads them with 14 runs batted in. Gonzalez hit a three-run home run Sunday against Trevor Cahill in the Dodgers' four-run third inning and added a double in the fifth inning.

"He's smoking the ball," Kemp said. "He's probably the best hitter in the league right now, at the moment."
